Preserving perishables in some of the world's most challenging conditions

Promethean Power Systems designs and manufactures refrigeration systems for cold-storage and milk chilling applications in off-grid and partially electrified areas of developing countries.

Our goal is to enable village-level chilling with a range of products that deliver high-quality produce to our customers. What excites us the most is that not only is this a great market need but also a win-win-win opportunity: a way to make a positive impact on quality and costs with dairy processors, better quality products for consumers, and increased opportunities for farmers in villages across India.

Promethean Chiller in Action

Customer Testimonials

Our milk spoilage has reduced by more than 90% after installing Promethean’s Rapid Milk Chillers in our Milk Collection Centres.

Mr. Taufiqur Rahmanformer CEO, Dairy Business, BRAC Bangladesh

"Running of diesel generators is capital-intensive and with prices climbing up, our costs have increased. Since deregulation of diesel will happen in the next one year, we have decided to go for an alternative energy option".

Rahul Kumarformer Managing Director, Amul

"We wanted a chilling system that could work without continuous electricity and generator sets, while factoring in our realities of collecting milk from thousands of small producers”. "With chillers that run on a thermal battery, we can save to the tune of Rs 6 a unit as compared to diesel gensets”.
